For Psion SIBO Machines (3a and onwards)

A program to allow repeated computation of stored formulae

Download here:


Copy the files to a /FRM directory (create if necessary), and then install from the Psion system screen.


The program allows you to input formulae into the Psion, compute the result using different variables, and output to a tillroll or a file.

Full help is provided, and the program allows formulae to be stored for later re-use.

All the software on these pages is FREE, and is provided with absolutely no warranty whatsoever. The software has worked for me in practice, but if it destroys your data/machine/life,then you have no recourse to me. I suggest that you ensure you have a COMPLETE backup of all your data before using any of these programs (it's a good idea in any event).
